To allwhom it may concern:

Beit known that I, JOHN E. EARLE, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new Improvement inRailway-Oar Vindow-Screen 5 and I do hereby declare the following, whentaken in connection with the accompanyin g drawings and the letters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,and represent, in-

Figure l, a front view of the device as placed in a window, Fig. 2, alongitudinal section of the window-screen; Figs. 3 and 4, transversesections of the slats, enlarged.

This invention relates to an improvement in window-screens speciallydesigned for railwaycars, the object of the invention being to preventthe entrance of smoke or dust, allow free circulation of air, and yetnot materially obstruct the view from the Window; and it consists in ascreen formed from vertical slats set diagonally, so as to slightlyoverlap each other and leave a space between, and the said slats formedfrom perforated, netted, woven, or other open material.

A B are the top and bottom of a frame 5 C D, the ends, which arepreferably constructed to set into the Window-frame beneath the sash Ewhen open. Into this frame are arranged several slats, a, more or lessin number, set

diagonally into the top and bottom portions of the frame, and preferablyset so that the edge of one will slightly overlap the other, and so asto leave a space between the slats, as seen in Fig. 2, in .substantiallythe manner as arranging the slats in a window-blind. These slats areformed from any open-work material, preferably wire-gauze or perforatedmetal. i

The edges, in case of wire, are protected or strengthened by theintroduction of a vertical wire as seen in Fio. 3 or b a bindino' asseen in Fig. 4. l

The open-work does not materially obstruct the View from the window. Thescreen should i be arranged so that the slats open to the rear.Therefore the motion of the car will create a stron g outward draftbetween the slats, sufficient to take away dust or smoke, which wouldJOHN E.
